          This process prevents stale authorization data from being used.
          If any authorization data for an account is changed at runtime, such as
          adding or removing roles and/or permissions, the subclass implementation
          of AccountStoreRealm should clear the cached AuthorizationInfo for that
          account through this method. This ensures that the next call to
          get_authorization_info(PrincipalCollection) will acquire the account's
          fresh authorization data, which is cached for efficient re-use.
